Question re CL need of funcall ?

2.simple funcall question

I've been playing with Lisp a bit to get a hang of the basics. In one
app I have a list of assorted items, some of which are functions that
may need to get called later. But I'm missing something in my syntax
to make it work.  I've reduced the question to:

  CL-USER> (funcall #'(lambda () (format t "called~%")))
  called
  NIL

Ok, and

  CL-USER> (nth 1 '("foo" #'(lambda () (format t "called~%"))))
  #'(LAMBDA () (FORMAT T "called~%"))

But combining these,

  CL-USER> (funcall (nth 1 '("foo" #'(lambda () (format t "called~%")))))
  ; Evaluation aborted

looks like it doesn't "see" the function as a function, confirmed by

  CL-USER> (functionp (nth 1 '("foo" #'(lambda () (format t "called~%")))))
  NIL

Why? And how to fix it?


Thanks..

4.Need a good CL implementation for experiments

Howdy,

I'm looking for a good CL implementation to experiment with.  My main
selection criteria are:

    Reasonably complete, with good ANSI compliance

    Small size

    Easy to build, easy to modify

I'm currently looking at CLISP, and GCL.  And perhaps ABCL, though I'd
prefer to stay away from Java.

By reasonably complete I mean that it doesn't have to be perfect, or
implemented every last detail of CLOS, for example.  Just "pretty good",
and heading in that direction.

By small size, I mean small code size for the compiler / interpreter and
standard libraries.  I'm going to need to wrap my brain around it, and
the smaller and more comprehensible the codebase, the better.  That also
ties into being easy to build and modify.

I would appreciate any advice given.

Cheers,

James Graves

5.Very rusty user needs help with Allegro CL -- today, packages

I am a very rusty user (retired 15 years, haven't looked at LISP of most of that time).  Makes me a luser, I guess.

Anyway, I downloaded the Allegro trial version, and dug up some old code (written around 1990) and tried to re-compile and load
it.  I'm having problems with the package system.  Either I've forgotten more than I thought, or something has changed.  Simplest
case:  here are the first few lines of the first file in my set:

;;; -*- Mode: Lisp; Package: USER -*-



(defpackage "utilities")  ; To insure existance.

(in-package :common-lisp-user)

;;; (use-package '(:utilities)) Change for ANSI CL

(in-package :utilities)

;;;  These are from "basicmacs".

(export '(qcar qcdr qrplaca qrplacd qcaar qcadr qcdar qcddr qcaaar qcaadr qcadar
               qcaddr qcdaar qcdadr qcddar qcdddr qcaaaar qcaaadr qcaadar qcaaddr
...

I don't even get this far -- NB this did work many years ago.

I get an error that the package "UTILITIES" doesn't exist.  If I then, at the top level, call make-package, I am told that
"UTILITIES" does exist.  But the file still won't compile or load.

So, what am I doing wrong.

PS I looked at the Allegro Lisp newgroup, but it seems to be dead or dying.
